+              This option controls how many connections are made to a
+              MySQL Cluster by a MySQL server acting as a cluster SQL
+              node. Normally, <command>mysqld</command> uses only a
+              single connection to the cluster, and the usual way to
+              scale out is by adding more SQL nodes
+              (<command>mysqld</command> instances). However, by setting
+              this option to a value greater than 1 (the default), it is
+              possible to scale out by allowing multiple MySQL clients
+              to leverage multiple connections made to the cluster by a
+              single MySQL server. The maximum possible is 63.
